hey guys, 2 wks ago this coming weekend i used my dethatcher and went over my lawn (which i doubt has EVER been dethatched) and my 1.2ac lawn took me 5 hours and probably about 60 loads emptying the bagger until it was finished. Anyway, last friday my uncle told me this weekend i should go over my lawn again and dethatch it a 2nd time, but in the opposite direction i initially dethatched it. He also told me after this second dethatching to follow up with Scotts Turf Builder with Halts Crabgrass Preventer (blue n white bag), then in a month go over lawn again with Scots Turf Builder Weed n Feed (yellow n white bag). Anyway, my biggest question is assuming my lawn hasnt ever (or within last 10 years) been fully dethatched, is it ok to dethtach it again a second time in the opposite direction or is one dethatching all thats nesc. no matter how much thatch is built up in the grass. i DO want my lawn to be one of the better/best looking lawns in the neighborhood, which shouldnt be hard beings no one does much besides mow.
